Jackery, a provider of premium rechargeable battery products for mobile devices, announced today the launch of two class-leading batteries, the Jackery Bar and Jackery Mini. Each battery takes up a minimal amount of space and provides users with considerable extra charging time for their favorite smartphone or tablet devices.

With 120 hours of extra operation time and a weight of only 5.4 ounces, the Jackery Bar is the world's smallest power bank with 2.1A output operating at 5600 mAh. The bar is fast charging, and ideal for users that need a powerful and compact mobile charging solution. It retails for $39.95 on Amazon.com.

The 2600 mAh Jackery Mini weighs less than three ounces and is currently the smallest external device battery in the world. Measuring only 3.7 by 0.9 inches, the Mini fits easily into a pocket or purse and offers up to 50 extra hours of operational time for device users. The Mini is capable of fully charging an iPhone 5 on one full cycle and currently retails for $29.95.

Each Jackery device features a durable and stylish aluminum case, which can sustain the rigors of frequent travel. The products hold their charge for up to six months due to the company's unique power lock technology, which allows the batteries to operate in a standby mode for up to six months.

"The Bar and Mini are powerful and fast-charging external batteries that give users on the go the peace of mind to know their devices can remain operable for extended periods," said Julie Wang, Chief Operating Officer of Jackery. "With our products, users get an immediate power boost that does not require scrambling to find an outlet. We envision consumers will purchase multiple products due to the convenience of on-the-go charging that is attainable at a very attractive pricing point. They'll buy a Jackery Bar for business trips and a Jackery Mini for fast charging around town and wonder how they ever lived without them."

In addition to iOS and Android devices, Jackery's products are also compatible with Windows phones, various smartphone and tablet platforms, multiple gaming devices, and MP3 players.
